I'm not positive but I'm pretty sure the 2013 lights won't fit the 2011 or 2012. The bumper is entirely different and like some said earlier the wiring is different too. I would look to someone like raxiom to come out with some aftermarket conversion or an all new twilight that looks similar. There are going o be a lot of people (including me) that are going to want those lights. That means money for whoever makes a kit first.

There was a roush car posted a while back with the new tails in a 12. They worked but didn't fit perfect. Had some gaps. Not sure on wiring as I don't really see Ford messing with that. But a bumper cover and then tail lights seems your in business

Yeah there was a pic of a 2011 V6 with the '13 tails. Here it is... There is a gap where the bumper angle is.
